PoE Mid-span/End-span Checker (NF-400PF)

Accurately detects whether PoE power comes from an endspan (1/2, 3/6 pairs) switch/router or a midspan (4/5, 7/8 pairs) PoE injector. A must-have on-site PoE tester for budget-oriented installers and engineers.

Due to it’s compact size, it easily fits in your pocket or tight spaces. Simply plug the cable into the RJ45 jack of the PoE detector or use the included testing cable to detect the PoE source.
